Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
음량 제어Volume control
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
통화상태에서 재생되는 오디오신호의 음량을 제어Control volume of audio signal played in call
3. 발명의 해결 방법의 요지3. Summary of the Solution of the Invention
오디오신호를 재생하는 수단과, 전화라인에 연결되며 전화라인의 전방을 거물하여 통화중 전압일시 통화상태신호를 발생하는 수단과, 전압검출수단과 연결되며 통화상태신호 수신시 음량제어신호를 발생하는 제어수단과, 오디오 기기와 연결되며 음량제어신호 수신시 오디오신호의 음량을 감쇄하는 수단으로 구성됨.Means for reproducing an audio signal, means for generating a temporary voltage signal during a call by being connected to a telephone line and tying the front of the telephone line, and generating a volume control signal when connected with a voltage detection means. Control means, connected to the audio device and comprises a means for attenuating the volume of the audio signal upon receiving the volume control signal.
4. 발명의 중요한 용도4. Important uses of the invention
전화 통화시 오디오 신호를 재생하는 장치의 재생 오디오신호를 감쇄하여 통화 효율을 향상시킴.Improves call efficiency by attenuating playback audio signals of devices that play audio signals during phone calls.
